Can't challenge Darwinism in any way.
Can't raise any worries about gay sex and/or contraception and/or abortion.
Can't assert your own faith as your highest personal value and can't suggest it is objectively good and true for all people.
Can't suggest humans might differ in any unique way from other animals (related to the Darwinist landmine).
Can't pick at the global warming "thing".
These are the "good citizen" hurdles of our day. Comply and you shall be "advanced." Resist and you shall be "old-fashioned."
